OIL-STOVE.

Application filed December 9, 1908.

Specification of Letters Patent.

Patented Apr. 12, 1910.

Serial No. 466,639.

T o all whom it 'may concern:

Be it known that I, FREDERICK CONRATII, of St. Paul, Ramsey county, Minnesota, have invented certain new and useful Improvements in Gil-Stoves, of which the following is a specification.

My invention relates to oil stoves or heaters used in freight cars containing vegetables or fruit to prevent them from freezing in transit and the object of the invention is to provide means, which will permit the convenient separation of the burner from the stove reservoir for cleaning or repairing purposes.

A further object is to provide an improved means for securing the stove chimney or stack thereon.

The invention consists generally in various constructions and combinations all as hereinafter described and particularly pointed out in the claims.

In the accompanying drawings, forming part of this specification, Figure 1 is a top view of an oil stove embodying my invention, Fig. 2 is a vertical, sectional view of the same, Fig. 3 is a detail view, illustrating a head light burner and means for supplying oil thereto.

In the drawing, 2 represents the oil reservoir having a base 3 and a top 1, wherein the burner 5 is arranged. This burner is of ordinary construction and tits within a circular opening 6 inclosed by the reservoir and has a wick 7 within an annular chamber 8, formed by the concentric inner and outer wick tubes 9 and 10. A nipple 11 is provided on the lower ends of the wick tubes communicating with the chamber between them and fitting within a sleeve 12 that is provided on the inner end of a horizontal pipe 13. The lower, threaded end of the nipple 11 depends below the sleeve 12 and is provided with a cap 14, by means of which the nipple is secured in the sleeve and the burner held in place on the base. No other securing means is provided for the burner and it is only necessary to loosen the cap 14 to allow the removal of the burner from the base for cleaning or repairs. The pipe 13 has a branch 15 extending up to the rcsei Voir 2 and the outer end of said pipe projects through the wall of the base and has a cap 16, which is removable, which allows access to the pipe.

Vhenever desired the oil may be drained off through the nipple or horizontal pipe without tilting the stove and upon ren'ioving the nuts a wire may be inserted into the horizontal pipe and into the nipple and the entire oil conducting passage thoroughly cleaned out without the necessity of removing the burner from the stove.

In Fig. 2E, I have illustrated a headlight burner Q0, having a nipple 21 on one side, passing through a sleeve 22. which communicates with an oil supply pipe Q3. The end ot' the nipple projects through the sleeve and has a locking cap 2li, which normally holds the parts securely together. (,)n the top of the stove I provide a chimney or stack Q5 in the t'orm ot' a .t'iustlun of a cone and composed preferably of sheet metal and having loop 2G at itsl lower end, forming one section o't' a hinge on each side o't' the stack, the other section consisting of a leaf or plate Q7 secured to the top of the stove and having loops 28, which register with loops 2G. A locking device 29 is provided for each hinge, slidable in a guide 30 and adapted to enter the loops Q6 and 28 and lock the stack on the stove. The locking devices are capable of being moved back and forth to lock both sides of the stack on the stove o1` release one side and permit the stack to swing on the hinge on the other side, or both hinges may be released to allow the stack to be removed entirely. The stack is provided with a bail 31 for convenience in carrying the stove. This arrangement of the chimney or stack and the means for attaching the same to the stove top forms the subject matter of a separate application and I make no claim to the same herein.

I do not wish to bc confined in this application to the specific coupling means provided :in connection with the burner andV reservoir, as the device shown vis capable of various modifications without departing from the spirit of my invention.

I claim as my invention 1. An oil stove comprising a reservoir having a central opening and a base, a burner litting within said opening, a nipple depending `from said burner, a feed pipe connected with said reservoir, a sleeve carried by said pipe and adapted to receive the threaded lower end of said nipple, said nipple projecting through said sleeve and forming an oil tight joint therewith, and a nut fitting the threaded end oi said nipple and locking it in said sleeve, said nut beine' readily removable to allow drainage and cleaning of said supply pipe and nipple Without disturbing said burner.

2. An oil stove comprising a reservoir having a central opening and a base, space being provided Within said base belovvjsaid reservoir, a burner fitting Within said opening, a nipple depending from said burner, a feed pipe connected With said reservoir and having one end projecting through the Wall of said base and provided at that end With a removable nut, a sleeve carried by the inner end of said pipe and adapted to receive the threaded lower end of said nipple and forming an oil tight joint with said nipple, the threaded end of said nipple projecting through said sleeve and a nut fitting said threaded end and locking it in said sleeve, said last named nut being accessible through the bottom of said base, and said pipe and nipple being adapted to be drained and cleaned by the removal of said nuts Without displacement of said burner.

3. A heater comprising a reservoir having a central opening and a base, a burner fitting Within said opening, a nipple depending from said burner, a feed pipe connected With said reservoir, a coupling means securing said nipple and feed pipe together below said burner and near the bottom of said base, said coupling means being accessible through said base and allowing drainage and cleaning of said feed pipe and nipple Without disturbing said burner.

t. A heater comprising a reservoir having a central opening and a base, a burner fitting Within said opening, a nipple depending from said burner, a feed pipe connected with said reservoir and projecting through the Wall of said base and having a removable closing means on its projecting end, a coupling uniting the contiguous ends of said nipple and said feed pipe and accessible through the bottom of said base, said coupling and closing means allowing the draining and cleaning of said nipple and feed pipe Without displacement of said burner.

In Witness whereof, I have hereunto set my hand this lst day of December 1908.
